Yaskawa GA800 E06 Fault Code — What It Means
The E06 fault code does not appear in available Yaskawa GA800 technical documentation or fault tables. Yaskawa uses alphanumeric fault codes that vary by firmware version and configuration, so the exact meaning of E06 on your drive must be verified in your specific unit’s manual or by reading the full fault description from the keypad display. The GA800 logs faults with timestamps and descriptions accessible through the parameter menu. Before troubleshooting, record your drive’s complete model number, specification code, serial number, and the full text shown on the display when the fault occurs, as this information is required for accurate diagnosis and support.
Common Causes
- Misread or partial code display The code may be part of a longer alphanumeric sequence (such as E.06 or A06) that requires scrolling the display to see completely.
- Firmware-specific or custom alarm Some GA800 firmware versions and application-specific configurations include fault codes not listed in general documentation.
- Parameter or configuration error A drive setup mismatch or modified parameter outside normal operating range can trigger unlisted alarm codes.
- Communication or network fault If the drive is networked or uses optional communication cards, the code may relate to fieldbus or protocol errors specific to your installation.
- Display or keypad issue A failing keypad or corrupted display memory can show incorrect or garbled fault codes that do not match the drive’s actual status.
Step-by-Step Fix
- Read the complete fault message from the GA800 keypad by pressing the Mode key to cycle through all alarm and status screens, noting every character and description displayed.
- Record drive identification by writing down the complete model number (printed on the nameplate), specification code, serial number, and all displayed fault text before clearing or resetting.
- Consult your drive manual for the fault code table specific to your GA800 model and firmware revision, checking both the quick reference and detailed alarm appendix.
- Check the fault log by navigating to the parameter group that stores historical alarms (consult your manual for the exact parameter number), which may show the fault name and timestamp.
- Inspect wiring and connections at the drive input and output terminals, control wiring, and any communication or option cards, looking for loose connections or damaged wire insulation.
- Verify parameter settings by comparing critical motor parameters (voltage, current, frequency) and application settings against your motor nameplate and machine requirements.
- Contact Yaskawa support with your recorded model, serial, and fault information if the code does not appear in your manual or if the fault persists after basic checks, as the code may require factory interpretation or a firmware update.
Parts Often Needed
| Part | Notes |
|---|---|
| Yaskawa GA800 keypad/display module | Amazon | Replacement operator interface if display is corrupted or unreadable. |
| GA800 control board or option card | Amazon | Required only if diagnostics confirm internal board fault, must match drive model and firmware. |
When to Call a Pro
Call a qualified Yaskawa technician or authorized distributor if you cannot locate the E06 code in your drive’s manual, if the fault reappears immediately after clearing, or if you are unfamiliar with VFD parameter programming and electrical diagnostics. Variable frequency drives operate at high voltage and require proper training for safe troubleshooting. Professional support is especially important when the fault code is undocumented, as it may indicate a firmware issue, internal board failure, or application-specific configuration problem that requires factory tools or replacement components matched to your exact drive revision.
